We at Metropolitan Waterworks and Sewerage System (MWSS) have carefully created a long-term Vision and Mission that will guide every aspect of our organization. This provides the framework for the goals we have established, the purpose we serve and the principles we stand for.

As the State’s chief agency on water and sewerage services, we will ensure that our concessionaires’ actions are equally guided by this Vision and Mission.

We derive our Mandate primarily from Republic Act 6234 which states the basic goals of the System and declares as its major policy the proper operation and maintenance of waterworks system to ensure an uninterrupted and adequate supply and distribution of potable water for domestic and other purposes and the proper operation and maintenance of sewerage systems in its service area which includes the whole of Metro Manila and parts of Cavite and Rizal.


Our Corporate Philosophy

We will always be mindful that we provide a service absolutely necessary for life and living, and that we will perform our role in the country’s development through honest, respectable hard work.  We fully believe that we can always strive to do our best to better serve the water and sewerage needs of our customer.

Our Corporate Policy

We institute these beliefs and values in our way of life, through leading by example and by making them an integral part of our performance management system.

Our Corporate Identity
